MC14541B Programmable Timer The MC14541B programmable timer consists of a 16stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, an automatic poweron reset circuit, and output control logic. Timing is initialized by turning on power, whereupon the poweron MC14541B MAXIMUM RATINGS (Voltages Referenced to V ) SS Symbol Parameter Value Unit V DC Supply Voltage Range 0.5 to +18.0 V DD V , V Input or Output Voltage Range, (DC or Transient) 0.5 to V + 0.5 V in out DD I Input Current (DC or Transient) 10 (per Pin) mA in I Output Current (DC or Transient) 45 (per Pin) mA out P Power Dissipation, per Package (Note 1) 500 mW D T Ambient Temperature Range 55 to +125 C A T Storage Temperature Range 65 to +150 C stg T Lead Temperature, (8Second Soldering) 260 C L Stresses exceeding Maximum Ratings may damage the device.
